VAT rules for Non-EU companies in the UK (Mumbai)

Dear All,

Does anyone know what the rules are with reference to VAT are for an Indian company exporting to the UK and selling under its own name via an Agency?
For example; If one were to send Jewelry from an Indian brand to the UK one would pay Duty and VAT on arrival, is the Indian Brand liable to pay another VAT when the end consumer, presumably a Brit citizen buys the product at a retail price?
Is it possible for a Non-EU company to have a VAT account in the UK?
Can a Non-EU person reclaim over charged VAT?

Thank you,
Nayomie
